Need to preserve nanosecond time stamps when converting disk to btrfs

I have a bunch of ext4 disks that I want to convert to btrfs, but I need to preserve the nanosecond time stamps. I've tested it on one disk but the time stamps for file modification are not fully preserved which has caused problems for my configuration. I want to convert the disks in place using the btrfs-convert command rather than moving the files to a new disk.

Thanks for any help

would it be possible to move the data to place storage and then convert the partition and move the data back over?

Yes, but I don't want to do that
